Title: Image forming device
Inventor: TAKAHASHI KAZUKI
IPC: G03G15/20
Filed: 1986-02-17
Abstract: PURPOSE:To enlarge the heat capacity of a fixing device and to improve fixability by forcibly conducting the current to the heat source of the fixing device at the prescribed timing for the prescribed time when the form is manually fed from a paper feeder. CONSTITUTION:When the form is inserted into a manual paper feed pedestal 12 on copying standby state, a manual heater control signal comes to a level L. If a microcomputer 31 judges the drop, the operation becomes a manual heater control mode. A timer in the microcomputer 31 starts its counting at the timing when an electrifier for electrostatic charger is turned on. At that time the temperature of a heat roller 23 in the fixing device 20 is checked. If it is below the prescribed temperature, a heater lamp 25 is forcibly turned on. If temperature exceeds the prescribed one, or if the timer ends it counting, the heater lamp 25 is turned off. Thus the heat roller can maintain the temperature to fix a toner image even if the thick form is manually supplied from the paper feeder 20 and heat is absorbed by the form when it passes by the heat roller.

IPC: H01L21/20
Filed: 1989-02-14
Abstract: PURPOSE:To dispense with a precise control of film thickness for each formation of a thin film and to facilitate integration of an element by a method wherein each layer of a semiconductor having larger electron affinity out of two kinds of semiconductors of a superlattice is disposed so that the width varies in inverse proportion to the square root of a distance from a prescribed place on a plane in one electrode toward the other electrode. CONSTITUTION:In a resonance tunnel diode wherein a plurality of superlattices each formed of a multilayer film of two kinds of semiconductors being formed on the same plane and different in the magnitude of electron affinity are arranged between electrodes 3, each layer of the semiconductor 1 having the larger electron affinity out of said two kinds of semiconductors 1 and 2 is disposed so that the width L varies in inverse proportion to the square root of a distance (x) from a prescribed place on a plane in one electrode 3 toward the other electrode. For instance, GaAs 1 or AlGaAs 2 is educed by an MOCVD method for a GaAs substrate 11, eduction is repeated by changing over material gases alternately, so as to form a vertical-type superlattice, and alloy electrodes of AuGeNi or the like are provided as the electrodes 3.

Title: Heat exchanger for air conditioning device
Inventor: YAMADA SHIGETO
IPC: F25B39/00
Filed: 1990-02-13
Abstract: PURPOSE:To improve the efficiency of heat exchange on the down stream side by a method wherein a staged part is formed on a fin in the vicinity of the central part of an air flow passage and turbulence is generated on the downstream side. CONSTITUTION:A stage part 9 is located in the vicinity of an approximately central part, in the direction of the air flow, of a fin 3 and inclined at an angle of approximate 30 - 45 deg. with the lamination direction of the fin 3. The two side parts of the staged part 9 are formed in parallel in a double level in the direction of lamination. Air caused to flow with the aid of a blower 6 heat-exchanges with the fin 3 as it flows along the fin 3 on the upper stream side. The temperatures, on both sides in the direction of width, of a flowing air layer are increased and the temperature of a central part is kept at a value lower than those on both sides. An air layer having a temperature difference is disturbed at the staged part 9 as it is bent thereat to produce turbulence. The air layer is approximately uniformized and air having temperature reduced to a value lower than that of air on both sides heat-exchanges with the fin 3 as it flows to the downstream side. Since a flow passage width extending at right angles with a staged part 9 surface is narrow, the velocity of flow of air flowing through the staged part 9 is increased to a value higher than that on the upper stream side to increase a turbulence effect.

CONSTITUTION:The signal level detecting circuit 1 detects input signals A0, B0, C0, and D0. The signal deciding circuit 2 decides whether a detected signal is larger or smaller than the set threshold value and outputs a logical value signal of '1' when the detected signal is larger or '0' when not. the signal adding circuit 3 adds the input signal of a signal circuit whose value is '1'. The branching circuit branches the added signal to a signal circuit other than its station circuit. Consequently, an multidirectional information interchange is made without decreasing the impedance nor level of the signal circuit.

Abstract: PROBLEM TO BE SOLVED: To sew a material fed into a machine by one or both of flat sewing and close sewing modes by selectively transmitting a driving power source to at least one of flat sewing and close sewing head assemblies and sewing the fed material by at least one of both head assemblies. SOLUTION: When a clutch assembly 17 is moved to a right side, the toothed inner part is engaged with the toothed outer surface of a shaft sleeve 7, the shaft sleeve 7 starts rotation and thus, a bent shaft 6 is also rotated and driving power is transmitted to the flat sewing head assembly. When the clutch assembly 17 is moved to a left side, a different part with spline is engaged with the part with the spline of a pulley 10 and the pulley 10 is rotated accompanying the rotation of the clutch assembly 17. Thus, the driving power is exerted to the close sewing head assembly. Also, when the clutch assembly 17 is positioned at a center position, both of the flat sewing head assembly and the close sewing head assembly are freely operatably engaged.

Title: Run length restricted coding and decoding using rigid resynchronization
Inventor: JONATHAN JAMES ASHLEY
IPC: H04N19/00
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To provide a rigid resynchronization pattern included in an RLL coding data by coding and decoding a run length restricted code, generating the rigid resynchronization pattern to put it into a channel bit stream and restoring the resynchronization pattern from an RLL coding bit stream. SOLUTION: A resynchronization generating mechanism 55 supplies a rigid resynchronization pattern which is put into a channel data bit stream by a write formatter 25. The resynchronization pattern is strengthened, when the RLL coding is carried out by an encoder 11 which excludes a specific pattern as a code word. A bit shift operation is applied to the resynchronization pattern to shift its head transition to its end transition, so that the pattern will not exceed the (k) restriction. Then the bit shift patterns are excluded from the code words which are generated by the encoder 11.
